Hi, it seems no one posted something about this, but I have encountered several times this bug and reproduced it very easily.
As shown in this screencast, when
- the referenced faces cease to exist, the Section silently gets deleted
- The faces are brought to a different component, the Section gets corrupted: it is impossible to re-link to the same or any different face: while the manipulators show but are ineffective, the tool interface responds as if nothing is selected. The Section has just to be deleted.
By deleting a Section I lose all settings about hatching and positioning, that should not be lost as a matter of principle.
